What treatment is best for managing skin troubles around the neck?

What kind of treatment should I receive for bumpy, uneven skin troubles or goosebumps around the neck?

Is anyone else like me worried about small, bumpy textures appearing around the skin on my neck and under my chin?

At first glance, it looks like goosebumps and millet. It is spread over a wide area with small bumps without the redness typical of blemishes, so every time I look in the mirror, my skin texture looks so messy and it is really stressing me out.

I could feel all the bumps when I touched it, and even after scrubbing, it didn't go down at all.

Should I receive skincare exosome or laser treatment?

If anyone has received treatment for unevenness or skin texture around the neck and seen their skin become smooth, please recommend a procedure.
